Awning window RH crank

Thanks for your patience during this busy summer season. We unfortunately don't have a version of the 39-074 in this size. Typically, the linkage in this sort of window has a fair measure of play, so you can get away with a difference in link arm size between the old and new operators. However, your difference is almost a full inch, which is definitely pushing it.

As it stands, I cannot be sure that our operator will work for you, but we don't have anything closer, either. This style of operator is just not as popular as it used to be. I am very sorry for the inconvenience. 

Sure, if you're handy and have the tools then I see no reason why that wouldn't work. I've never personally tried it myself, but the main function of that link arm is to just connect the operator gearing to the linkage in the window. As long as it can do that then you should be okay.
